In: Biology
Calcium is used for a fuck ton of stuff, a lot of which I almost certainly don’t know, but I can give some things.
Calcium is combined with other atoms to form most of the structural parts of bones and teeth.
Calcium serves a key role in the nervous system – without calcium, every single nerve in your body is incapable of communicating with other nerves, thereby rendering you dead.
Calcium is used in large amounts by muscle cells – every time the muscle wants to contract, it has to release a flood of calcium across every cell in that muscle. This is also true of the heart.
Calcium is vital to many cell signalling pathways – allowing the cell to respond to stimuli like hormones.
Calcium is used in the blood clotting process.
Calcium is required for sperm to fertilise eggs.
